1914 Tue Apr 15 15:31:09 1997 Stan Shebs <shebs@andros.cygnus.com>
1916 * remote.c (get_offsets): Don't use scanf for interpreting
1917 response to qOffsets.
1919 Tue Apr 15 14:51:04 1997 Ian Lance Taylor <ian@cygnus.com>
1921 * gdbserver/Makefile.in (INSTALL_XFORM): Remove.
1922 (INSTALL_XFORM1): Remove.
1923 (install-only): Use $(program_transform_name) directly, rather
1924 than using $(INSTALL_XFORM) and $(INSTALL_XFORM1).

1941 Mon Apr 14 11:55:27 1997 Geoffrey Noer <noer@pizza.cygnus.com>
1943 * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
1944 since gcc automatically includes it
1946 Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com>
1948 * procfs.c: Substantial (but incomplete) changes to support
1949 sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo
1950 struct now has substructs like struct flt_ctl instead of
1951 just a fltset_t and has a ctl_fd, status_fd, as_fd, and
1952 map_fd instead of a single fd. Non-sysv4.2mp procfs models
1953 still have the structs and multiple fds, but don't use the
1954 entire struct and the four fds all point to the same thing.
1955 We use PROCFS_USE_READ_WRITE to decide whether to talk to
1956 procfs with reads/writes or use ioctl instead. We use
1957 HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
1958 multiple fds or not. PROC_NAME_FMT is split out into
1959 CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
1960 STATUS_PROC_NAME_FMT.
1962 (procfs_notice_signals): now a necessary wrapper around
1963 (notice_signals): which are the new guts for noticing signals
1964 (open_proc_file): gets a new flag arg used in sysv4.2mp to
1965 determine whether or not to attempt to open the ctl_fd.
1966 (procfs_read_status): new local function, reads procfs status
1967 (procfs_write_pcwstop): new local function, writes a PCWSTOP
1968 (procfs_write_pckill): new local function, writes a PCKILL
1969 (unconditionally_kill_inferior): remove signo since we now
1970 just call procfs_write_pckill().
1971 (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
1972 (proc_iterate_over_mappings): the whole function is ifdefed
1973 on UNIXWARE to keep things readable.
1975 Expanded the syscall_table to include new potential sysv4.2mp
1976 members. Note that all ifdefs of UNIXWARE should be eliminated
1977 if possible or renamed to describe what's being selected for a
1978 bit better. Sysv4.2mp and IRIX both have SYS_sproc so the
1979 IRIX specific code now also checks it's not UNIXWARE.
1981 * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
1982 HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
1983 * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
1984 "/debug/%d" as PROC_NAME_FMT used to be
1986 Wed Apr 9 11:36:14 1997 Jeffrey A Law (law@cygnus.com)
1988 * mn10300-tdep.c: Almost completely rewritten based on mn10200
1990 * config/mn10300/tm-mn10300.h: Likewise.
1992 Tue Apr 8 10:45:24 1997 Stu Grossman (grossman@critters.cygnus.com)
1994 * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}: Remove
1995 remote-pa.o from TDEPFILES. Nobody uses it, and besides, it's a
1996 lousy out-of-date clone of remote.c.
1998 Fri Apr 4 08:21:21 1997 Stu Grossman (grossman@critters.cygnus.com)
2000 * remote.c: Fix problems realized while showering.
2001 * (hexnumlen): Add prototype. Use max, not min.
2002 * (remote_write_bytes remote_read_bytes): Fix max packet size
2003 calculations to properly account for packet overhead. Also handle
2004 (probably rare) case where remote_register_buf_size isn't set.
2006 * remote.c: Fix doc for `C' and `S' commands to indicate full
2008 * (remote_ops extended_remote_ops remote_desc remote_write_size):
2010 * (remote_fetch_registers remote_write_bytes remote_read_bytes):
2011 Record size of response to fetch registers command, use this to
2012 limit size of memory read and write commands.
2013 * (push_remote_target): New function to make it possible to have
2014 another target switch to the remote target.
2015 * target.h: Add prototype for push_remote_target.
2016 * sh-tdep.c (sh_frame_find_saved_regs): Fix sign extension bugs
2017 for hosts which default to unsigned chars (such as SGI's).
2018 * (_initialize_sh_tdep): Don't set remote_write_size. It's now
2019 handled automatically in remote.c.
2021 Thu Apr 3 15:10:30 1997 Michael Snyder <msnyder@cleaver.cygnus.com>
2023 * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
2024 find_pc_sect_function(), find_pc_sect_partial_function(): new
2025 functions for debugging overlays; pc without section is ambiguous.
2026 * breakpoint.[ch]: add section pointer to breakpoint struct;
2027 add section argument to check_duplicates(); check section as well
2028 as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
2029 breakpoint_thread_match(), bpstat_stop_status()];
2030 add section argument to describe_other_breakpoints();
2031 use INIT_SAL() macro to zero-out new sal structures;
2032 make resolve_sal_pc() fix up the sal's section as well as its pc;
2033 match on section + pc in clear_command() and delete_breakpoint();
2034 account for overlay sections in insert_breakpoints(),
2035 remove_breakpoint() and breakpoint_re_set_one();
2036 all this to support overlays where a PC is not unique.
2037 * exec.c: change xfer_memory() to handle overlay sections.
2038 * findvar.c: change read_var_value() to handle overlay sections.
2039 * frame.h: declaration for block_for_pc_sect() [blockframe.c].
2040 * infcmd.c: jump_command() warns against jumping into an overlay
2041 that's not in memory. Also use INIT_SAL() to initialize sals.
2042 * infrun.c: wait_for_inferior() sets a flag to invalidate cached
2043 overlay state information; Also use INIT_SAL() to init sals.
2044 * m32r-rom.c: modify load routines to use LMA instead of VMA.
2045 * m32r-stub.c: mask exit value down to 8 bits; screen out any
2046 memory read/writes in the range 600000 to a00000, and ff680000
2047 to ff800000 (hangs because nothing is mapped there); fix strcpy().
2048 * maint.c: maintenance command "translate-address" supports overlays.
2049 * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
2050 * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
2051 this constitutes gdb's internal overlay mapping table. Add macro
2052 ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
2053 Add function find_pc_sect_section().
2054 * printcmd.c: modify print_address_symbolic() with overlay smarts;
2055 modify address_info() with overlay smarts; add function sym_info()
2056 to support the INFO SYMBOL command (translate address to symbol(s));
2057 modify disassemble_command() to work on unmapped overlays.
2058 * source.c: use INIT_SAL() to initialize sals.
2059 * symfile.[ch]: change generic_load() to use section's LMA address
2060 instead of VMA address, for overlay sections.
2061 Add numerous functions for finding a PC's section / overlay,
2062 translating between VMA and LMA address ranges, determining if an
2063 overlay section is mapped, etc. Add several user commands for
2064 overlay debugging. Add support for a "generic" form of automatically
2065 reading overlay mapping info from the inferior (based on the default
2066 (simple) overlay manager which Cygnus provides as an example).
2067 * symtab.[ch]: add functions find_pc_sect_symtab(),
2068 find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
2069 for lookup; modify lookup_symbol and decode_line_1() to use them;
2070 modify find_function_start_sal() to account for overlay sections;
2071 add macro INIT_SAL() for initializing struct symtab_and_line.
2072 * target.c: fix a comment in the declaration of target_ops.
2074 Thu Apr 3 10:31:12 1997 Mark Alexander <marka@cygnus.com>
